Higher-Order Topological Phase in the Two-Dimensional Type-IV Magnet MgCrO
Xiaorong Zou, Hyeon Suk Shin, Yanmei Zang +4
Type-IV two-dimensional (2D) magnetism-a newly classified collinear magnetic phase featuring nonrelativistic spin degeneracy and spin-orbit-coupling-induced momentum-dependent spin…
Sustainability-Aware Discovery of Dual-Atom Hydrogen Evolution Catalysts via a Unified Machine Learning Framework for Activity and Carbon Cost
Yanmei Zang, Hyun Gyu Park, Gi Beom Sim +8
Catalyst discovery for green hydrogen has optimized activity alone, deferring economic and environmental costs to stages where they disqualify otherwise promising candidates. Here…
Floquet-Engineered Odd-Parity Altermagnetic Higher-Order Topology in a Two-Dimensional Antiferromagnet CrCH
Xiaorong Zou, Hyeon Suk Shin, Baibiao Huang +5
Periodic driving provides a platform to dynamically tailor quantum states of matter, yet its impact on symmetry-protected topological phases remains incompletely understood. Here,…
Second-order topology in two-dimensional azulenoid kekulene carbon lattices
Xiaorong Zou, Hyeon Suk Shin, Chang-Jong Kang +5
The discovery of higher-order topological insulator (HOTI) has established a new paradigm for understanding symmetry-constrained boundary electronic states. Here, based on first-pr…
Stochastic Loop Corrections to Belief Propagation for Tensor Network Contraction
Gi Beom Sim, Tae Hyeon Park, Kwang S. Kim +6
Tensor network contraction is a fundamental computational challenge underlying quantum many-body physics, statistical mechanics, and machine learning. Belief propagation (BP) provi…
